Usage

General Description

Tetrabutylammonium thiocyanate is a quaternary ammonium salt that is commonly used as a phase transfer catalyst and inorganic reagent. Its chemical formula is C16H36N2S, and it is a white crystalline solid that is soluble in polar solvents such as water, methanol, and acetonitrile. Tetrabutylammonium thiocyanate is used in organic synthesis as a reagent for the conversion of alcohols to thiocyanates, and can also be used as a source of the thiocyanate anion in various chemical reactions. It can act as a weak base and is commonly used in combination with other reagents to promote a variety of chemical reactions in the laboratory. Additionally, it is used in analytical chemistry as a reagent for the determination of various metals and as a corrosion inhibitor in metalworking fluids.

SPECTROSCOPIC PROPERTIES OF THE Eu3+ ION IN THE 3Eu(NCS)6 CRYSTAL

The IR Raman and fluorescence spectra of Eu3+ in the 3Eu(NCS)6 crystal are reported.The results indicate that only one point symmetry of Eu3+ ion is present in the crystal.The presence of the 5D0 -> 7F0 transition in the fluorescence spectrum and the lack of strong vibronic lines indicates that the local symmetry of Eu3+ ion is lowered from Oh.The temperature dependence of fluorescence lifetimes of %&D0 level has been measured.The mechanism of fluorescence quenching is briefly discussed.

Ion exchange synthesis and thermal characteristics of some [N +4444] based ionic liquids

Eight salts, derived from tetrabutylammonium cation [N+ 4444] and inorganic anions like BF4-, NO 3-, NO2-, SCN-, BrO 3-, IO3-, PF6- and HCO3- were synthesized using the ion exchange method. These ionic liquids (ILs) were characterized using thermogravimetry, differential scanning calorimetry and infrared spectroscopy. Thermophysical properties such as density, volume expansion, heat of fusion, heat of solid-solid transitions, specific heat capacity and thermal energy storage capacity were determined. The total of heat of solid-solid transitions observed below the melting points exceeded the heat of fusion in some cases. The thermal conductivity of the samples was determined both in solid and liquid phases. High values of thermal energy storage capacity and handsome liquid phase thermal conductivities made many of the ionic liquids under investigation were recommended as Thermal Energy Storage Devices (TESDs) as well as heat transfer fluids.
